Hi Olushola,

You're almost there. In effect, you're code looks for the @ symbol, but that symbol can appear anywhere. So you need to tell your expression to look for the @ symbol as the start of the string you're interested in.

The ^ character looks to the start of a string but that will still pickup anything after an @ symbol. So I tried adding a check for whitespace but this doesn't work. Then I tried the tab character which is 't'.

So @[^t] added to your expression should pass the challenge.

On a small note, I think twitter handles also allow numbers, so in reality you would want to add '\d' after your '\w'. You don't need it to pass the challenge though.

Hope that helps
